What If-

"Do you know what I fear the most? I'm scared it's not a dream. The dream feels so real. What if that was a memory, a missing memory, a memory trying to forget. Do I hurt people? No... Did I kill people? That child... Is he die?" Mai Anthony.

Mai Anthony was haunted by nightmares for 12 years because of an accident she had when she was 5 years old. An accident that made her suffer from PTSD and Hemophobia. Unfortunately, Mai can't remember clearly what happened at that time and her family seems to cover it up with the excuse of her kindness. Mai only remembers that she once hurt a boy and felt bad for him.

Aaron Porter has everything anyone could envy. Smart, handsome, popular, and also rich. His life looks perfect but he is tied to the past. His father still considers him a delinquent because in the past he used to get into trouble, he couldn't move on from his ex-girlfriend in high school. And long before that, he had been involved in an accident with a little girl while playing together.

What if when the two meet again and find out that their brief encounter in the past turned out to have an unfinished story? What will Mai do when she finds out that it was Aaron who traumatized her? What will Aaron do when he finds out that his little lie had ruined someone's life?
